STM32 LQFP64 Minimum System: common questions

What microcontroller does the STM32 LQFP64 Minimum System use?

The STM32 LQFP64 Minimum System is built around the STM32F401RETx, from the STM32 family.

How big is the STM32 LQFP64 Minimum System PCB?

The STM32 LQFP64 Minimum System measures 69.4 × 37.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the STM32 LQFP64 Minimum System?

34 components, from 16 distinct parts. The full bill of materials is listed on this page.

Where can I download the STM32 LQFP64 Minimum System design files?

From the mekatronik-achmadi/example_collection repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the STM32 LQFP64 Minimum System design in my own project?

The repository has no license, so all rights stay with mekatronik-achmadi. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the STM32 LQFP64 Minimum System without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
